I see strange responses in the comments to me... I really liked the HE and I've tested it right beside the HD600 with wired btr5 and balanced cables for both. No eq. HE was juuust a bit worse than 600 whilst being almost 3 times cheaper. I would've picked HE immediately, if I didn't have German Maestro GMP400 already, which is quite on par with HD600, if not better in some cases.
